BURNER FOR INCANDESCENT MANTLES.

SPECIFICATION forming part of Letters Patent No. 764,155, dated July 5,1904.

Application filed March 5, 1903.

To all whmn it ntay concern:

Be it known that I, VICTOR H. SLINAoK, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, haveinvented certain new and useful Improvementsin Burners for Incandescent Mantles, of which thefollowing is aspecification.

One object of the present invention is to provide a burner which shalleffect and consume or burn a mixture of air and gas in those proportionsand relations which give a substantially maximum heating power, andtherefore in connection with an incandescent element a high lightingefliciency.

Another object of the invention is to provide improved means forregulating the mixture of air and gas.

Other objects of the invention are to provide features of constructionwhich benefit the operation of the burner.

To these and other ends hereinafter set forth the invention, stated ingeneral terms, comprises the improvements to be presently described andfinally claimed.

The nature, characteristic features, and scope of my invention will bemore fully understood from the following description, taken inconnection with the accompanying drawings, forming part hereof, and inwhich Figure l is a central sectional view of a burner embodyingfeatures of the invention. Fig. 2 is a top or plan View of the same. Fig3 is a side elevational View, drawn to a re- 3 5 duced scale, of theburner. Fig. 4 is a view of the under side of the burner-head, and Fig.5 is a top view of the shank of the burnerhead.

In the drawings, 1 is a tubular burner- 4 head. It is shown as somewhatlarger in diameter at its base than it is at its top.

2 is a toothed disk arranged at the outlet of the burner-head with thepoints of its teeth in contact with the inner rim thereof.

3 is a downwardly-tapering guide arranged beneath the toothed disk.

4 is a truncated hollow pyramid arranged Serial No. 146,275. (No model.)

between the guide 3 and the inlet portion of the burner-head and havingits side walls reversely curved or warped, as at 5 and 6, and providedwith a series of slots 7, extending continuously from its top to itsbase.

As shown, the disk and the guide are made of separate pieces and areheld together by a screw 8, whose head engages the truncated pyramid 4.

The shank 9 of the burner-head is tubular and of considerably lessdiameter than the burner-head. At its top it is shown as flaring outwardand as provided with a notched flange 10, Fig. 5, which by a movement ofrotation is engaged by or disengaged from projections 11, Fig. 1, on theburner-head, so that the head and shank may be connected ordisconnected.

12 is an air and gas mixing tube, having openings 13 in its base, whichlatter is shown as of larger diameter than the rest of the tube.

14 is a regulator or screw arranged radially and so as to project intothe tube 12. As shown, it can be caused to extend clear across the tube12, and it is, generally speaking, located about midway of the height ofthe burner and as shown. The tube 9 is slotted, as at 15, so as toaccommodate the screw 14: and permit of the removal of thesuperstructune from the gas and air mixing tube 12. This slot alsoprevents rotation of the head of the burner, which would be undesirablefor reasons that are well understood and among which mention may be madeof the fact that it is common practice to aline the side support for themantle with parts of a lantern in order to avoid a multiplicity ofshadows.

16 is a sleeve rotatably mounted on the mixing-tube and provided withslots, which may be caused to correspond more or less with the slots 13and in that way regulate the effective size of the latter. andconsequently the amount of air-admission space afforded thereby.

17 is a perforated guard of larger diameter than the sleeve, and 18represents means for supplying a jet of gas.

19 is a gallery carried by the burner-head and. provided with means 20for holding a mantle-support.

In operation the warped shape of the wall of the pyramid 4 imparts to itsuch stiffness and strength that the slots 7 may be cut from its base toits top, and this is advantageous, because it affords free passage forthe mixture of gas and air, and since these slots 7 are in alinementwith the spaces between the teeth of the disk 2 the mixture of air andgas is thoroughly effected and freely delivered to be burned. Themixture is supplied to the flame broken up by passing between the teethof the disk 2, and this imparts steadiness to the flame. The guide 3serves to direct the mixture through the openings between the teeth. Byadjusting the screw 14 the mixture can be regulated,because the more ofthe screw that projects into the tube the more is the velocity of themixture retarded, and since the supply of gas is constant the supply ofair is diminished, and by causing less of the screw 14 to project intothe tube the velocity of the mixture is increased and more air is takenin. The fact that the guard 17 is of larger diameter than the air-mixingtube gives it such a large surface that the sum of the area of all theholes in it is substantially equal to or not less than the area of theopenings 13. Thus there is an ample supply of air through the holes inthe guard. Furthermore, the described burner by reason of itsconstruction and the relative arrangement of its parts produces amixture of air and gas and burns the same under conditions calculated todevelop the maximum heat possible with the gas supplied, so that with anincandescent element excellent lighting results are effected.

It will be obvious to those skilled in the art to which my inventionappertains that modifications may be made in details without departingfrom the spirit thereof. Hence Ido not limit myself to the preciseconstruction and arrangement of parts hereinabove set forth, andillustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. A burner comprising a tubular burnerhead, a toothed disk arranged-atthe outlet of the burner-head with the points of its teeth in contactwith the rim thereof, a downwardlytapering guide arranged beneath thedisk, a truncated hollow pyramid arranged between the guide and theinlet portion of the head and having its side walls reversely curved orwarped and provided with slots extending continuously from its top toits base, and a gas and air mixing tube arranged to discharge into theopen end of the pyramid, substantially as described.

2. A burner comprising a bu rner-head having a detachable shank, anotched flange and complemental projections between the head and shank,a toothed disk arranged at the outlet of the head, a truncated hollowpyramid. arranged between the disk and the inlet portion of the headand. provided with slots ex tending continuously from its top to itsbase, and a gas and air mixing tube penetrating said shank,substantially as described.

3. In a burner the combination of the cylindrical unobstructed air andgas mixing tube with an endwise-adjustable regulator narrower than thebore of the tube and arranged radially of the same, substantially asdescribed.

In testimony whereof I have hereunto signed my name.
